If you watch This Is Us, then you know that the show basically doubles as a weekly cry-fest. Aside from the phenomenal acting, there are also quite a few tragic twists in each episode. Now that the series has returned for its second season, officially resuming our sob sessions, we've decided to round up the saddest moments. Of course, as we learn more about Jack's death this season, we're sure there will be plenty more to add to this list later on. We suggest playing the show's equally heartbreaking soundtrack while you read.
